BOTTOM-DUIVIPING BUCKET.

To all whom 'it 'may concern:

Be it known that I, GUsravUs L. STUEB- NER, a citizen of the UnitedStates, and a resident of Flushing, in the county of Queens and State ofNew York, have in vented certain new and useful Improvements inBottom-Dumping Buckets, of which the following is a specification.

This invention relates to bottom dumping buckets. Its organizationcomprises a bucket with a movable bail, connected by links to the doorsthereof and means for locking the bail to the bucket when the doors areswung to their closed position, and other means to maintain the bailwith its appurtenances at various angles, to vary the inclinations ofthe doors when lowered from the body of the bucket. A stationary bail isalso provided for the bucket, the vertical cross axial plane of whichpasses preferably through the center of gravity of the bucket, and thesimilar plane of the movable bail is distant from the said plane of thestationary bail, so that the chains for the bails will not interferewith each other.

The buckets are particularly useful for handling concrete, but may beused for any other material.

In the accompanying drawings Figure l represents an elevation of abucket exemplifying the invention, Fig. 2 is a top plan view of Fig. l,Fig. 3 is a view similar to Fig. 1 with doors in a lowered position,Fig. 4 shows, a right hand side view of Fig. l, and Fig. 5 is a bottomplan view of Fig. 4.

The bucket exemplifying the invention is shown with the body having thesides 21, ends 22, upper reinforcing band 23 with the supporting angle24, lower reinforcing band 25 and lower crossbraces 26, the ends ofwhich latter are connected to the angle irons 27 extending from theinner faces of said ends 22. Angle irons 28 extend from the sides 2l andsupport the stationary bail 29. A hook 30 with the chain 31 is shownsuspending the vertical stationary bail 29. Hinge straps are fastened tothe ends 22 of the bucket and are straddled by the journal lugs 36extending from the doors 37 and 38. The lugs 36 with their doors arehinged to said hinge straps 35 by means of the hinge pins 39.

Each of the doors '37 and 38 comprise a cover 42, which is supported onan inverted box shaped frame 43, and a lip 44 extends from the lowerface of one of the covers 42 Specification of Letters Patent.

and bears up against the lower face of the cover of the accompanyingdoor when they are in a closed position. Plates 45 with the pins 46 andplates 47 with pins 48 extend from the box shaped frames 43 of the saiddoors, the plates 47 with their pins 48 being somewhat more distant fromthe inner end of their door 38, than 'the distance of the plates 45 withthe pins 46 from the inner end of the door 37.

Angle irons 50 and 5l extend from the sides 2l of the body of the bucketand constitute guides for the operating and movable bail to bedescribed. Openings 52 are formed in said angles for stop pins 58 whichare suspended on chains 54 having their upper ends fastened to the sides21 of the bucket. Guide pockets 55 are fastened to the sides 2l of thebucket for the pins 53 when the latter are not in operative position.

Angle irons 60, 61 and 62 are fastened to the sides 2l of the bucket,the angle irons and 6l, being located between angle irons 50 and 51. Theangle irons 60 constitute stops for the said operating and movable bail,and the angle irons 6l and 62 constitute guards to prevent the bendingof the links to be described should they be struck when using thebucket.

Links 65 have their lower ends fulcrumed on the pins 46 of the door 37,and links 66 somewhat longer than the links 65 have their lower endsfulcrumed on the pins 48 of the door 38. The upper ends of each pair ofsaid links 65 and 66 arefulcrumed on the pins 67 extending from the hookends 68 of the operating and movable bail 69. The movements of the pins67 are main tained in vertical planes, by virtue of the hook ends 68 ofoperating bail being guided between the guides 5() and 5l. The locationsof the pins 46 and 48 with the lengths of the links 65 and 66 maintainthe doors 37 and 38 at approximately equal angle with the bottom edge ofthe bucket when the said doors are lowered therefrom. When the doors arein their closed position links 65 are in vertical positions and thelinks 66 are inclined thereto. The lower inner openings 70 of the hookends 68 are formed with the walls that are arcs of circles describedfrom the centers of the pins 67, andthe said hook ends are engaged withlocking pins 71 extending from the bucket, when the doors are locked ina closed position with respect to the opening through the body of thebucket. The said pins 7l With said hook ends (3S constitute a lockingdevice. The hook ends GS extend from the sides of the bail and thelatter are formed With the main portion 72 thereof.

A ring hook support 73 is fastened to the main portion 72 of theoperating bail, and bears on the supporting' angle Q4, When the doors 8Tand 3S are in a closed position and the hook ends G8 are engaged by thelocking pins 7l. Hooks 74C with the chain 75 are connected With theoperating and movable bail 69.

To explain the operation of the invention the bucket can be consideredwith the doors 3T and 8S loWeredfrom the body thereof, as shown in Fig.3, and the bucket suspended with the chain 3l supporting the stationarybail 29 and the chain 75 supporting the operating' and movable bail G9,the hook ends 68 bearing on the angle irons 60. The bucket is non'lowered to receive its charge and at the same time the chain 75 ishauled in Which Will close the doors 37 and 3S against the body of thebucket, and the said hook ends G8 will become engaged with the lockingpins 7l firmly holding the doors in place. The chain 75 may non'v bepaid out While the bucket With its doors closed is bearing on a support,when the operating bail Will fall to the left side of the locking pin 67and bear on the supporting angle 2t, by reason of the left side of thesaid operating bail being' heavier than the right side. lWhen the bailis thus supported on the angle 2l it is securely locked with the lockingpins 7l. Then the bucket is to discharge its charge the chain 75 ishauled in Which Will cause the bail (39 to assume its vertical positionand allenY the hook ends to disengage from the locking pins 7l, byvirtue of Which said hook ends will drop to and bear on the angle irons60 and the doors Will drop to the positions shown in said Fig. 3.

The angles of the doors 37 and 38 With the bottom of the bucket When intheir lowered positions, can be varied by inserting the pins 53 in thediiferent openings 52.

The invention may be modified by using only one door with the bodythereof and one link like 65 or 5G at each of the sides thereof.

Having described my invention what I claim as new therein and desire tosecure by Letters Patent of the United States is:
